Change of Season, Change of Fur



The Arctic is an area in the far northern part of the Earth. The climate there is harsh. Summers are short, and winters are long, dark, and cold. No trees grow there. Still, there are many forms of life in the Arctic. There are plants, such as grass and moss, as well as animals such as birds, fish, and mammals.



Mammals are warm-blooded animals. "Warm-blooded" means that the animal's body temperature stays about the same no matter what the air temperature is. Hair or fur helps keep animals' body temperature regulated.



How do animals manage to survive in the Arctic? Some of them migrate in the winter. They travel to a warmer part of the world, and return when the winter is over. Others find a safe, warm place to sleep through the winter. Many animals, however, remain all year long. They have to find food, and they have to do it without becoming someone else's dinner. To help escape predators, some animals have developed ways of camouflaging themselves.



Three types of Arctic mammals use camouflage. These are the Arctic fox, the Arctic hare, and the weasel. These animals grow two new coats of fur every year. In the winter, their fur is white. The animals are almost invisible against the white snow and ice that fills their world. As spring and summer arrive, the white coat falls out and a coat of brown or gray fur grows in. In fact, the species of Arctic fox that lives furthest north has a white coat all year long. a fox standing on a ledge



The weasel's camouflage includes a trick. The tail has a dark spot on it. Birds that hunt weasels mistake the dark tail tip for the head. When they dive for what they think is the head, they are really diving at the tail.



In their white, furry disguises, Arctic foxes and weasels hunt smaller animals, such as lemmings and hares. Foxes will also eat plants if that is all they can find. Arctic hares do not hunt. They eat plants, such as leaves, moss, twigs and bark. In winter, Arctic hares use their powerful hind legs to break through ice and snow in order to reach these plants.



Weasels, foxes, and hares don't have to do anything to make their coats change color with the seasons. The adaptation plays a large part in how they survive in this difficult climate.
